I'm really worried because my diastolic blood pressure is consistently 90 or higher, even though my systolic is usually between 120 and 130. I've had a renal scan and tests for creatinine and urine protein, and everything came back normal. What could be causing this high diastolic pressure when everything else seems fine?

Given your high diastolic blood pressure (90+ mmHg) and normal systolic pressure (120-130 mmHg), along with normal renal scan, creatinine, and urine protein results, consider lifestyle modifications to manage blood pressure: increase physical activity, reduce sodium intake, follow the DASH diet, manage stress through relaxation techniques, get adequate sleep (7-8 hours), and maintain a healthy weight
